ALSA: control: Minor optimization for SNDRV_CTL_IOCTL_POWER_STATE
Long long time ago, before the proper PM framework was introduced, it
was still possible to reach SNDRV_CTL_IOCTL_POWER ioctl during the
power off state. This ioctl existed as a main control for the suspend
resume state in the past, but the feature was already dropped along
with the standard PM framework. Now the read part,
SNDRV_IOCTL_POWER_STATE ioctl, returns practically always D0, and we
can do some minor optimization there.
